Globally, combustible gas leaks can trigger severe fire and explosion incidents in industrial sites, commercial areas, and domestic environments, posing threats to life and property. As critical equipment for preventing such accidents, the appropriate positioning of combustible gas detectors is paramount. So where exactly should these detectors be installed? Below, Yiyuntian Eranntex outlines the key considerations.

　　Industrial Premises: Precise Placement for Production Safety

　　Within industrial settings, the installation location of combustible gas detectors must be determined based on specific production processes and gas leakage risks. Take petrochemical enterprises as an example: refineries and chemical plants contain significant quantities of flammable and explosive hydrocarbon gases such as methane, ethylene, and propane. In these environments, detectors should be installed in areas prone to gas accumulation.

　　Within storage tank farms, detectors should be fitted atop and around each tank. This is because gas leaks may occur during filling and emptying operations, and gases readily accumulate at tank tops due to density differences. Furthermore, pipeline junctions and areas near valves are critical locations for detector installation. These points are high-risk areas for gas leaks. Should a leak occur, the combustible gas detector can promptly detect it and trigger an alarm, alerting personnel to take measures such as closing valves or activating ventilation systems to prevent the escalation of incidents.

　　Within production workshops, detectors should be strategically positioned according to specific equipment and process flows. For instance, detectors must be installed near reactors, distillation columns, and similar apparatus where combustible gases may be generated during operation, enabling real-time concentration monitoring. Concurrently, detectors should be fitted at workshop ventilation inlets and exhaust outlets to ensure timely detection of combustible gases diffusing from other areas.

　　Commercial Areas: Safeguarding Public Safety, Preventing Hazards Before They Arise

　　Commercial zones are densely populated, and a combustible gas leak could have catastrophic consequences. Therefore, the proper installation of combustible gas detectors is crucial for ensuring public safety.

　　In catering establishments such as restaurants and hotels, kitchens represent the primary area for combustible gas usage and are key locations for detector installation. Natural gas or liquefied petroleum gas is frequently used during cooking. Factors such as ageing pipelines or faulty stoves may lead to gas leaks. Detectors should be positioned near gas hobs, gas pipeline connections, and poorly ventilated areas—such as kitchen corners or beneath ceilings. This enables early detection of leaks, preventing fires or explosions caused by excessive gas concentrations.

　　In large commercial buildings like shopping centres and supermarkets, beyond kitchen areas, combustible gas detectors should also be installed in warehouses and equipment rooms utilising gas appliances. For instance, rooms housing gas boilers or gas air conditioning units may generate combustible gases during operation. Detectors can promptly identify leaks, safeguarding the entire building.

　　Home Environment: A Cosy Haven Requires an Essential Safety Barrier

　　The installation of combustible gas detectors in domestic settings is equally crucial. With increasing numbers of households utilising natural gas for cooking and heating, gas leaks pose a significant potential threat to home safety.

　　The kitchen is the primary location for installing combustible gas detectors in the home. Detectors should be positioned near the gas hob, either beneath the ceiling or above the wall, as natural gas is lighter than air and will rise upon leakage. This positioning enables more timely detection of leaked gas. Additionally, avoid installing detectors directly in the path of cooking fumes, as these can impair the detector's sensitivity.

　　If a household has a bathroom or utility room containing a gas water heater, detectors should also be installed in these areas. Gas water heaters may experience incomplete combustion during operation, producing flammable gases such as carbon monoxide. Detectors can promptly identify such hazards, safeguarding the lives of household members.

　　The installation location of combustible gas detectors must be selected judiciously according to the specific setting and purpose. Whether in industrial premises, commercial areas, or domestic environments, detectors must be positioned correctly to maximise their early warning capabilities. This effectively prevents accidents caused by combustible gas leaks, fostering a secure and dependable environment for daily life and work.
